After coupling, the locking nut is tightened to prevent the claw connection from loosening on its own. This makes the coupling particularly suitable for professional compressed-air systems with increased connection-safety requirements.\u003c\/p\u003e\u003cp\u003eThe coupling has a 42 mm claw spacing with double safety cams. The coupling body is made of galvanized steel\/cast iron and the locking nut is made of brass. An oil-resistant NBR seal is used. The temperature range is −40 °C to +100 °C and the maximum operating pressure is PN 16. Depending on the version, the coupling is available without a safety collar, with a safety collar, or with a crimp-ferrule collar. According to Krause K+K, the series is compatible with all MODY safety screw couplings.\u003c\/p\u003e\u003chr\u003e\u003ch5\u003eBenefits\u003c\/h5\u003e\u003cp\u003e✅ Safety hose coupling according to DIN 3238\u003cbr\u003e✅ Locking nut prevents accidental loosening\u003cbr\u003e✅ 42 mm claw spacing with double safety cams\u003cbr\u003e✅ Galvanized steel\/cast-iron coupling body\u003cbr\u003e✅ Brass locking nut\u003cbr\u003e✅ Oil-resistant NBR seal\u003cbr\u003e✅ Available without safety collar, with safety collar, or with crimp-ferrule collar\u003cbr\u003e✅ Temperature range −40 °C to +100 °C\u003cbr\u003e✅ Compatible with MODY safety screw couplings\u003cbr\u003e✅ Maximum operating pressure PN 16\u003c\/p\u003e\u003chr\u003e\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\u003cdiv style=\"overflow-x:auto;border:1px solid #d9d9d9;border-radius:10px;\"\u003e\u003ctable style=\"width:100%;border-collapse:separate;border-spacing:0;min-width:680px;\"\u003e\u003cthead\u003e\u003ctr style=\"background:#f3f3f3;\"\u003e\u003cth style=\"position:sticky;left:0;z-index:2;background:#f3f3f3;padding:10px;text-align:center;\"\u003eFeature\u003c\/th\u003e\u003cth style=\"padding:10px;text-align:center;\"\u003eValue\u003c\/th\u003e\u003c\/tr\u003e\u003c\/thead\u003e\u003ctbody\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eDesign\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eHose coupling with locking nut\u003c\/td\u003e\u003c\/tr\u003e\u003ctr style=\"background:#fafafa;\"\u003e\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eStandard\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eDIN 3238\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eClaw spacing\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003e42 mm\u003c\/td\u003e\u003c\/tr\u003e\u003ctr style=\"background:#fafafa;\"\u003e\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eClaw design\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eDouble safety cams\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eCoupling body\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eSteel\/cast iron, galvanized\u003c\/td\u003e\u003c\/tr\u003e\u003ctr style=\"background:#fafafa;\"\u003e\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eLocking nut\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eBrass\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eSeal\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003eNBR, oil-resistant\u003c\/td\u003e\u003c\/tr\u003e\u003ctr style=\"background:#fafafa;\"\u003e\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eTemperature range\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003e−40 °C to +100 °C\u003c\/td\u003e\u003c\/tr\u003e\u003ctr\u003e\u003ctd style=\"position:sticky;left:0;background:#fff;padding:10px;text-align:center;\"\u003eHose connection\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003ewithout safety collar \/ with safety collar \/ with crimp-ferrule collar\u003c\/td\u003e\u003c\/tr\u003e\u003ctr style=\"background:#fafafa;\"\u003e\u003ctd style=\"position:sticky;left:0;background:#fafafa;padding:10px;text-align:center;\"\u003eOperating pressure\u003c\/td\u003e\u003ctd style=\"padding:10px;text-align:center;\"\u003emax.
